Net Run Rate (NRR) is a cricket statistic used to rank teams with equal points in tournament tables. It measures the difference between a team's scoring rate and the scoring rate of teams against them.

공식

NRR = (runs_scored / overs_faced) - (runs_conceded / overs_bowled)

RS: Runs scored (runs) — Total runs batted by team
OF: Overs faced (overs) — Overs of bowling faced (1 over = 6 balls)
RC: Runs conceded (runs) — Runs given up while bowling
OB: Overs bowled (overs) — Overs bowled by team

단계별 가이드

1NRR = (Runs Scored ÷ Overs Faced) − (Runs Conceded ÷ Overs Bowled)
2Positive NRR means the team scores faster than they concede
3Negative NRR means they concede runs faster than they score
4All-out teams are counted as using their full allocation of overs

자주 묻는 질문

What is a good NRR?

Positive NRR is good; higher is better. 0.5+ is strong. Negative NRR indicates team is underperforming.

How is NRR used?

Tiebreaker in group stages (cricket tournaments). If two teams have equal points, higher NRR wins group.

Is NRR biased?

Somewhat. Early runs matter less; late runs matter more. Large wins inflate NRR; narrow losses reduce it.
